Honestly, if it’s something you need in the next month or so I’d just order from a U.S. supplier.
I would but it's not an option for me. sourcemore still has a few 2010 coil heads still in production. Not available in the USA anymore at a reasonable price, if you can find at all. There was one place that used to sell them and stock regularly but they stopped stocking that stuff now. So China it must be.
I'll prolly wait till February.
